Gaura lindheimeri is a new plant for me. This one is nicknamed "Whirling Butterflies."
These are perennials (depending on winter temperatures), hybrids of a North American wildflower. Drought tolerant, prefers full sun, blooms all summer. Perfect border plant. They come in white or pink.
The only thing in life more charming than a well-structured and well-designed perennial border is a well-structured, well-designed girl.
